Ruislip 300k ride report

Last Sunday I rode 300k for the first time - and got back within time, so that's another tick in the PBP qualifying box...

The first 40k were pretty vile; not entirely sure why as it didn't seem to be particularly nasty route-wise. It was however absolutely freezing, and my feet in particular were really suffering, which I guess might have been the problem. Note to self: always take the damn overshoes. There was a point around here when I seriously considered bailing (on the grounds that if I felt this rotten now how was I going to feel in 200k time...) but thankfully a hot cross bun & squash at the first control, and the sun finally starting to provide some actual heat, improved things.

Unusually for me, I reached the Woburn control to find plenty of other riders still milling around (I have hitherto tended to be way off the back), which was also a bit cheering. A lot of the next bit was really beautiful, especially through Woburn Park where there were deer! And blue sky, trees, birds, etc etc. Pretty!

As a rule, when someone says to you "It's a lot flatter after X" they may mean one of several things:

1) I have no idea what it's like but I want to cheer you up.
2) I have no idea what it's like but I want to cheer myself up.
3) Last time I rode this there was a tailwind after X.
4) Last time I rode this I had 4 1/2 chocolate bars & 2 bananas at X so I was bloody flying.
5) I can't remember anything after X from the last time I rode this so I'm assuming that it was unexceptionable rather than that my brain is protecting me from the horror.

What they virtually never mean is:

6) It's a lot flatter after X.

However! On this occasion the chap who said this was actually, it seems, reasonably correct, & the first half of the bit after Woburn was nice and fast.

Rode with a chap on an Airnimal visiting from Hong Kong for a while - his first Audax, and he seemed to be doing pretty well. The last 20k or so to the next control (T-somewhere Farm Centre) it was getting a bit windy, and I was definitely starting to feel it.

Baked potato & beans at the Farm Centre, & a chat to various other people feeding themselves, then off for another fairly tough 40k into the wind. Arrived at the Little Chef feeling pretty wiped, but the All-Day Veggie Breakfast (which can be made vegan!) was a very good thing for revitalising purposes. Plus I put my bars back to where they had been before I started fiddling with them before the ride (oops) & found that suddenly lots of the aches went away. Evidently Mr Hewitt knows rather better than I do about bar height...

Bit of a drag out of the Little Chef control, and saddle slippage for about the millionth time had me stopping to fiddle with it. Whereupon I hooked up with a small group of riders from Willesden for a bit, which was nice. I also discovered the secret to overcoming my lack-of-nerve issues on descents: be sufficiently tired that the concern about Messy Head-Impact Death is overwhelmed by the concern about Not Wasting Any Of My Precious Potential Energy. Brakes? What're those?

It was roughly this point at which my legs started behaving themselves, at last. Inadvertently rode straight off the front of the Willesden guys (sort of assumed they were behind me, & then looked back & no sign), with very little input from the brain other than a polite suggestion that my legs might like to keep going round for a bit. 25k to the next control felt great. Baffling! Another chat with a bunch of folk at the next Little Chef (with a slightly grumpy waitress), and intended to start out with Pete, Hilary, & someone else, but turned out that my legs were still behaving & rode straight of the front there as well.

The last stage was 60k, of which about 45k was absolutely fine, and the last 15 was OKish - not physically that much of a struggle, but mentally I was getting to the AM I NEARLY THERE YET? stage. Over the Chilterns was reasonably short-and-sharp (which I like better, I think, than long-and-gradual), and conquered without too much hassle with the lovely granny ring. Took an alternate route back (via A413, A40, B4something) on Local Advice, which was prob faster but a bit dull. Mind you, I don't like country lanes in the dark; nice big streetlit A-roads suit me better.

Brief circuit round Ruislip (whoops) & into the Arrivee. Ate sandwiches & then set off for the 30k home, having missed my last tube by about 80min. The last half of that was v tough indeed, despite nice chats with bus drivers ("Where have you been to?" "300k around Ruislip" "You are a very impressive woman!" Bless.), but worth it for pleasure of Own Shower and Own Bed. So with that & the 12k to the start from Ealing, close to 350k for the day.

It was v nice to be sufficiently of a speed with at least some folk (albeit the back markers!) that I could chat to people at controls. I quite like riding on my own on Audaxes (partly because it's about the only time I get to spend on my own ever when I'm not supposed to be Doing Something; partly because I like to let my legs set their own pace) but it's reassuring to encounter other people at intervals. Also I think this is the first Audax I've done that I wasn't lanterne rouge :-)

What was your time, and the official time that you beat?

(I agree with the bus driver)

Well done lady! Bloody impressive!

Wow -- that really is seriously amazing...

I didn't even know people *could* cycle that far. :-)

600k=

40min on a 747
2hr on a TGV
5hr in a car at motorway speeds

That's a long way on a bike! How long would it take you?

(Still very impressed BTW).

Unfortunately I am slow enough that I'm not likely to get that much sleep in, which is going to slow me down on the second half.

You may want to think about whether that computes... If being tired will slow you down significantly, having a kip might reduce rather than increase your overall time. I did a very rough back-of-the-envelope calculation and figured that a 2h sleep at the halfway point would have to improve your speed by slightly less than 2km/h to break even. That's with all sorts of bogus estimates, mind, so you'd want to think more carefully, but it's probably worth pondering?

[identity profile] steer.livejournal.com 2007-04-12 03:58 pm (UTC)(link)
Will you sleep at all in that time?

Did you go all the way up Brick Hill before Woburn? I can imagine nearly anything feels flatter after that, I found it one hell of a slog on the Oxford-Cambridge. And the steep bit in the park itself was a complete bugger.

I too have a lack-of-nerve on descents, and I think I was close to entirely wearing out my back brake-blocks on Monday. It's silly: on a steep descent I'll brake myself back to around 16 mph and feel terrified, but as soon as it flattens out a bit I don't even notice 20mph as fast, and 25+ isn't all that scary.

My longest in a day is still 90 miles, so I'm as impressed as the bus drivers, if not more so!

I think the knowledge I'd have to be a bridesmaid covered in grazes for even a minor bump slowed me down even more than usual this week. Must get some more practice in. Will be easier once Mike has new bike. His current one can't get up the slope from an underpass at the moment without the chain slipping, and it has a million other little things wrong with it too.

I'm in awe of this - well done.

You are mental.

In a good way ;)

Oh, I kind of envy you. Although not enough to actually, you know, get on a bike...

[identity profile] martling.livejournal.com 2007-04-12 02:31 pm (UTC)(link)
Wow. You've now cycled further than I've flown - was hoping to bag my 300km this summer. :)

[identity profile] martling.livejournal.com 2007-04-12 02:56 pm (UTC)(link)
Sure I can! I, er, just can't get started again...

[identity profile] martling.livejournal.com 2007-04-12 03:29 pm (UTC)(link)
Well, if you model flapjacks as thermals, then you should be able to use the Späte-Dewing-Pirie-MacCready theory calculate your optimal speed to cycle, based on the curve relating your cycling speed to energy consumption, and the expected rate of energy gain from the next flapjack. You could factor in headwinds and slopes in exactly the same way we do sink.

[identity profile] martling.livejournal.com 2007-04-12 03:48 pm (UTC)(link)
Still, it raises some interesting parallels. E.g. you preferred the climb up the Chilterns short and sharp, which is essentially the same thing as us flying fast through sink - you increase your sink rate further, but it's advantageous in the long run to get out of it faster.

(A good graphical explanation of the theory I'm on about is here, incidentally, since you do reportedly have your geek hat on)

[identity profile] martling.livejournal.com 2007-05-04 11:32 pm (UTC)(link)
It seems like it should always be optimal to take the hill as fast as possible. What is "possible" is just a bit complicated, I suppose. It presume it depends on the remainder of the course, because if you have just one short hill left to the finish then you can utterly knacker yourself on it, but if you've another 100k to do after then you need to be more careful.

Ultimately I suspect this is in some way analogous to the various proposed refinements to simple speed-to-fly theory, which attempt to take into account the fact that one's altitude is finite. I have yet to read up on these in detail, but I gather the executive summary is just the intuitive "get less picky about lift as you get lower".

Score :D

Love the 'after X' thing!

Nice one. We'd have had a go at that had we not flaked out in the 200k - I shall just have to enjoy it vicariously.

[identity profile] huskyteer.livejournal.com 2007-04-12 04:44 pm (UTC)(link)
Blimey. That's a fair step on a motorbike, let alone a human-powered bike! Well done!

you have me beaten now: 143 miles is the furthest i ever managed. had no company for that, but the weirdest part of it was that the hardest section was the flattest. the wind was blowing the wrong way across romney marsh.

[identity profile] jvvw.livejournal.com 2007-04-12 05:58 pm (UTC)(link)
Sounds like you cycled from my parents house (in Ruislip) and past my house (near Woburn, I sometimes drive home from work through the deer park) as well as back again, that's really impressive :-)

By the way, did they mark the km markings on the road? I thought I saw a km marking in pink chalk on the road driving home but was didn't see properly.

Actually saw them a bit better yesterday and think they're for the Flitwick 10K that happened recently.

Coo. What stops me jumping on to try this sort of distance is a) sense :) and b) the weather issue (I can see that some conditions would not be fun) and c) having sensible (for cycling) roads. I'd probably also prefer going to somewhere rather than 'just' doing a loop.

Do they think recumbents are cheating?

This is not related but you're the second google hit for the query
solaris ssh cursor keys
(at least from where I am querying -- I think it changes by country)

It was quite a surprise since the page in question is in O'reilly.
